The former Mainz goalkeeper moved to Anfield in the summer for a relatively modest £4.7m fee.

But Klopp evidently reckons he can turn the former Manchester City youth player into a future star, and told him as much ahead of his transfer.

Karius told Goal: “When we spoke, he told me that he’s known me for a long time, that I have all the qualities needed to succeed at Liverpool, and he is very confident that I will develop even better with him.

Which Liverpool transfers are most likely to happen in January?

Karius, still only 23, was one of the brightest prospects in the Bundesliga after excelling with Mainz.

But he says Jurgen Klopp's energy and enthusiasm persuaded him to pick Liverpool over several other suitors.

“When I heard Klopp wanted me, I was really excited because it felt like a huge reward after everything I’d been through, and also because I know how hard the manager works for success.

"I was watching Liverpool already like many people in Germany, who wanted to follow what he was doing in the Premier League.

“You could already see last season the way of playing at the club changed and even though the results now and then weren’t always as good as what people wanted, you could notice what he was building and that the team was stronger.

"I knew that in the summer, with the time he had to create his team with transfers and pre-season, that he would really transform Liverpool.

"I believed in everything he told me. I had a really good talk with him, and it was not a hard decision to make.”
